As described in the refineConfig section, ATG Search can calculate refinements based on the query results, in order to offer the end-user a quick way of narrowing the search.
The max value specifies the maximum number of facet properties to return, even if the facet set could generate more. The default value is 0, which means no calculation is made.
<query refineConfig="name" refineConfigDefault="default"
refineConfigMapKey="key" refineConfigMapProp="prop" refineMax="max"
refineTop="top" refineMin="min"
